6 claims. (o1. 16-129) This invention relates to adjustable hinges, more particularly those for supporting doors of substantial weight.

The invention is particularly adapted, but is not limited, to the adjustable support of soundproof doors employed in buildings tending to settle, or subject to considerable vibration, such as those in which aircraft engines and other parts are tested, and where machinery is operated. As a result of uneven settling of the building,` vibration and other causes, the door frames of such buildings sometimes become warped, so that for one reason or another there occurs ment of the doors relative to the frames, with a resultant drop in eiicieney of the sound-proofing between the door and the frame. The invention also has to do with refrigerator and other Sometimes, due to improper preparation of the parts to be installed, manufacturing tolerances, etc.; if no nexibility of installation of the door were possible. the door would be mounted in improper or inefficientl sealing relation to the frame.

It is accordingly an object of my invention vto provide a hingesupport for a door enabling adjustments to be made at the time of installation and thereafter from time to time in various directions yto establish and to reestablish any desired relation between ciated frame.

Additional objects are to provide' an adjustable hinge construction which is extremely simple, embodying a minimum. of parts which a displacethedoor and thev asso- *form of a casting and has upper may be produced inexpensively and readily assembled and disassembled, and is sible for adjustment at all times.

Another object is'to provide a universally adjustable door hinge construction.

A further object is construction enabling the door to be adjusted in a direction transverse to the hinge axis.

Further objects and advantages of the invention will appear as the description proceeds.

The invention will be better understood upon reference to the following description and the accompanying drawings, in which:

Fig. l is a fragmentary elevation of a door mounted in accordance with my invention;

Fig. 2 is a fragmentaryvelevation showing the hinge mounting in detail;

Figs. 3 and 4 are fragmentary sectional views taken as indicated by the lines 3-3 and 4-4, respectively, in Fig. 2; n

Fig. 5 is a fragmentary perspective view of the hinge mounting; f

readily acces-V t to provide a door hinger Fig. 6 is similarV to Fig. 4 but is less broken away and also shows how a door mountedon the hinge construction cooperates with a door frame; and

Fig. 7 is a fragmentary sectional View of a modified form of hinge strap eye and bearing therefor. Y

While there is shown and described herein certain specific structure embodying the invention, it will be manifest to those skilled in the art that various modifications and rearrangements of the parts may be made without departing from the scope of the invention, and that the same is not limited to the particular forms herein disclosed.

Referring now more particularly to the drawings, there is shown at 2B a wall such as, for example, a concrete wall having a vdoor frame 22 at a side of which arehinge bracketsupporting plates 24 adjacent the upper and lower ends 2S of the hinge stile of the frame. if desired, the hinge brackets may be bolted directly to the wall or to the frame itself. The frame 22 is adapted to receive a door 32 supported by means of upper and lower hinge straps 34. These straps are bolted as at 38 or otherwise suitably secured to the door 32 and connected to a'pintle bracket Ml The number of straps may bel as will appear. variedY as desired. y

The pintle bracket 4l) is preferably bolted or otherwisesecured as at l2` to the respective sup- 24 or to the wall or frame, as the Said bracket is preferably in the and lower arms 44 with substantially registering holes' therethrough. Above the upper hole 46 and below the lower hole is a cavity 48 having a back wall 50 and two side lwalls 52 and open at the front and at the top and bottom, respectively. The ceiling 54 of the lower arm and the floor 5S of the upper arm are serrated as shown at 51 substantially from one to the other of the side walls or lugs 52.

For each cavity is there ing block 58 having a bore 60 substantially smaller than the openings 45 in the pintle bracket arms Mi and adapted to slidably fit the shank E2 of a pintle bolt 64 and having in one face thereof serrations adapted to interfit with the serrations 51 of the pintle bracket 40. The length and width of the adjusting block 58 are both substantially less than the length and width, respectively, of the ceiling 54 and the door 56, and the adjusting block accordingly may be adjusted toward and away. from the back wall 50 of eachl opening 48 and toward and awayv from porting plate case may be.

is provided an adjusttinuous gasket the respective side walls 52 of the bracket, within the limits determined by the wall of each opening 46, cooperating with the shank 62 of the pintle bolt 64. The walls 52 of each opening 48 are tapped at and receive set screws 12 adapted to clampingly engage opposite edge faces 'I4 of the adjusting block 58 to securely maintain the same in the desired position of adjustment. The set screws may be of the socket head or any other suitable type. Although I have shown two set screws in each wall 52, placed so as to be effective irrespective of the adjustment of the adjusting block, obviously one or any other suitable number of set screws, suitably spaced, could be provided in each wall 52. The screws will positively prevent shifting of the block parallel to the grooves or serrations, and, with the nut 16, will prevent the blocks from movement away from the serrated surfaces 56 so that, once the device is set up, it is impossible for the pintle bolt to shift accidentally relative to the pintle bracket.

Each hinge strap 34 has an eye 80 through which the shank 62 of the pintle lbolt 64 passes, between the arms 44 of the pintle bracket. overall height of the eye is substantially less than the distance between the arms 44, and accordingly suitable spacing means is placed about the shank and between the eye and the arms 44. The eye may be formed in any suitable manner. In the form of the invention shown in Figs. l to 6, the eye maybe formed by curling the hinge strap 34 and rests on an end thrust bearing 82 'under which are disposed two or any other suitable number of shims or washers S14. Four or any other suitable number of additional washers 84 are disposed between the top of the eye and the upper arm 44.

I have already explained how each adjusting block may be adjusted in two directions at right angles to each. other, both normal to the axis of the holes 45 in the arms 44. It is possible for either block 58 to be adjusted dilerently from the other block 58, due to the tolerances -between the blocks and the bolt and between the washers 84 and the bolt, so that the bolt may be secured with its axis inclined to the axis of the holes 46. It is also possible to adjust the eye Bil upward or downward. Thus, to adjust the eye downward, the nut 'l5 is removed, the bolt 64 is raised until the free end thereof is suiliciently high to enable one of the lower washers 84 to be shifted to the upper group of washers d4, and the bolt is reinserted and secured by the nut 16. To adjust the eye upward, this same procedure is followed except that one of the upper washers is shifted to the lower group of washers. The eye 80 can thereby be adjusted in a direction parallel to the bolt.

Thus it is apparent that with my novel adjustable hinge construction it is possible to adjust the pintle bolts toward or away from the wall, toward or away from the door frame and up or down.

Instead of forming the eye by curling an end of the strap 34, I may cast the strap as shown at 95 and form the same with an eye 92 countersunk at 94 to receive combined end and radial thrust bearings 96 which preferably project slightly above and below the eye for unhampered engagement with adjacent adjusting washers.

It will be observed that in one form of door installation to which the invention is adapted, there may be provided in the door framea con.-

l adapted to engage an inner corner portion |02 of the door, and an Youter portion of the door may be provided with a similarcontinuous gasket |04 adapted similarly to cooperate with a continuous corner portion |66 of the door frame. As has 4been indicated above, there may be such a relative displacement of the door and frame as to materially reduce the eciency of the sound-prooiing or heat insulating struction described above and shown on the drawings to reestablish the proper relation between the door and the frame.

Various modifications may suggest themselves to those skilled in the art without departing from the spirit of my invention, and, hence, I do not wish to be restricted to the specific form shown or uses mentioned, except to the extent indicated in the appended claims.
